Abstract
High efficiency video coding (HEVC) has three units such as coding unit (CU), prediction unit (PU), and transform unit (TU). It has too many complexities due to improve coding performance. We propose a fast algorithm which can be possible to apply for both CU and PU parts. To reduce the computational complexity, we propose based on rate distortion cost of CU about the parent and current levels to terminate the CU decision early. In terms of PU, we develop fast PU decision based on spatio-temporal and depth correlation for PU level. The Experimental results verify that the proposed algorithm provides up to 51.70 % of time reduction for encoding with a small loss in video quality, compared to HEVC Test Model (HM) version 10.0 software.
